(aka: Orbexilum pedunculatum) We love finding great garden plants that are virtually unknown in commerce, and no plant exemplifies that better than the North American (Illinois south to the Gulf Coast and west to Texas) native Psoralea psoralioides. This baptisia relative is usually found in acidic praries and in filtered open woods, although our seed strain came from a Nash County, NC bog, where it grew with Trillium pusillum. We have had superb success on ammended dry sandy loam, where it forms an 18" tall specimen, like a miniature baptisia, topped starting in mid-May (NC) with hundreds of short terminal spikes of tiny lavender flowers...very cute!
